Apple is offering the first public beta of iOS 14.4 for iPhone and iPadOS 14.4 for iPad tonight. It comes 24 hours after the first developer beta.
The first beta of iOS 14.4 is especially interesting for those who have a HomePod mini, even with the beta version. The update takes full advantage of Apple’s U1 speaker chip. There are now visual, acoustic and haptic effects when transferring songs from a HomePod mini to an iPhone 11 or 12 (which also has the U1). When an iPhone is near the HomePod mini, a haptic beat begins. It speeds up as the iPhone gets closer until the interface for transferring a song between HomePod mini and iPhone appears.
There is currently nothing new with the iOS 14.4 (public) beta. To see if the next betas have any.
If your device is configured to receive public betas, go to Settings> General> Software Update. The first public beta of iOS 14.4 is displayed.
Your iPhone or iPad is not configured for public beta and you are interested? Open Safari and navigate to beta.apple.com. Sign in with your Apple account and follow the instructions. This consists of downloading a profile to put your iPhone or iPad on the beta channel.
